JOSEPH NOSS, OF THREE RIVERS, MICHIGAN.

'I'OOL-SI-IARPENER.

To all whom it may concern:

Be it known that I, J OSEPH Noss, a citizen of the United States,residing at Three Rivers, Michigan, have invented certain new and usefulImprovements in Tool-Sharpeners, of which the following is aspecification.

This invention relates to improvements in tool Sharpeners.

The main objects of this invention are: First, to provide an improvedtool sharpener which is portable, and, at the same time, may be verysecurely held in position for use without attaching to a support.Second, to provide an improved tool sharpener which is very simple andeconomical in structure and very effective.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure 1 is a perspective view of my improved sharpener. Fig. 2 is alongitudinal section thereof taken through the clamping member. Fig. 3is a vertical central transverse section.

In the drawing, similar reference numerals refer to similar partsthroughout the several views.

Referring to the drawing, the holder 1 is preferably formed of a pieceof sheet metal folded or bent into a loop between the sides of which thepiece of abrading material 2 is arranged. The front edges of the sidesare turned outwardly to form flange-like tool guides or rests 3. Theserests are adapted also to serve as supports for the holder when in use,one rest serving as a support when the other is in position to serve asa guide or tool rest. The rests are provided on their edges with teeth4. adapted to engage the table or other support 5 on which the holder isplaced in use. The clamp 6 is formed of spring material provided withinturned ends 7, adapted to engage over the edges of the holder, asclearly appears from the drawing. The ends of the clamp member arepreferably V-shaped so as they draw the edges of the clamp they forcethem together Specification of Letters Patent.

upon the piece of abrading material. A loop 8 is formed in the clampwhich not only provides a spring for drawing the clamp upon the edges ofthe holder, but also serves as a finger piece, and in grasping thisfinger piece when in use, extra tension is provided on the clamp, thusvery effectively and securely clamping the abrading material in theholder.

In use, the finger piece 8 of the clamp is grasped, as stated, andpressure applied thereto which forces the teeth 4 into the support 5 onwhich the device rests, so that it is not likely to shift or twistthereon, which would be a very serious objection as it would change theposition of the tool guide or rest 3 relative to the tool beingsharpened, which is held against the rest, as is indicated by dottedlines in Fig. 3.

My improved sharpening device is especially designed by me forsharpening beveled edged tools, such as shears, although it is adaptedfor various other tools.

My improved sharpening device is very simple and economicalL instructure, and is, at the same time, very effective and convenient touse. It can be easily held without the necessity of attaching it to afixed support.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a sharpening device, the combination with the loop-like holderhaving yielding sides, said sides having inclined flangelike tool guidesor rests at their forward edges, said rests being adapted to serve assupports for the holder, the outer edges of said rests having engagingteeth thereon; an abrading member arranged in said holder; and a clamphaving inturned ends adapted to embrace the ends of said holder, and anoffset loop adapted to serve as a finger piece.

2. In a sharpening device, the combination with the loop-like holderhaving yielding sides, said sides having inclined fiange like toolguides or rests at their forward edges, said rests being adapted toserve as supports for the holder, an abrading member arranged in saidholder; and a clamp having inturned ends adapted to embrace the ends ofsaid holder, and an oifset loop adapted to serve as a finger piece.

3. In a sharpening device, the combination with the loop-like holderhaving yielding sides, said sides having inclined flangelike tool guidesor rests at their forward edges, said rests being adapted to serve assupports for the holder, the outer edges of said rests having teeththereon, an abrading member arranged in said holder; and a clamp havinginturned ends adapted to embrace the ends of said holder.

e. In a sharpening device, the combination with the loop-like holderhaving yielding sides, said sides having inclined, flangelike toolguides or rests at their forward edges, said rests being adapted toserve as supports for the holder; an abrading member arranged in saidholder; and a clamp having inturned ends adapted to embrace the ends ofsaid holder.

In a sharpening device, the combination with the holder formed of apiece of sheet metal folded into a loop with its ends turned outwardlyinto inclined, flange-like tool guides or rests, said rests beingadapted to serve as supports for the holder; an abrading member arrangedin said holder; and a clamp having inturned ends adapted to embrace theends of said holder.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
